Surprised you say that, Bill. Many people have observed that, given an initial "preinfusion period," there is little difference in the average flow rate when heavily-tamped shots and lightly-tamped shots are compared.Billc wrote: lightly tamped coffee allows more flow and the pressure is decreased, tightly tamped coffee restricts water more resulting in higher pressure
For instance, at the 2006 SCAA show, Michael Teahan did a short presentation on his experiment comparing 10lb tamped shots to 250lb tamped shots. No difference in shot timing or average flow rate.
